For Westerners schooled in the four basic tastes (sweet, sour, salty and bitter), the concept of umami, or the "fifth taste," may be a new one. Umami describes foods with an inherent savoriness. We taste umami in foods like Parmesan cheese, seaweed, miso, and mushrooms, which contain high levels of the amino acid glutamate. It's a complex, elemental taste, and perhaps our craving for it is driven by some biological imperative.
Both amniotic fluid and breast milk are high in the amino acids that deliver the taste of umami, which may prime us to seek its flavor throughout life.
More About Umami
Umami means "pleasant savory taste" in Japanese. The popularity of umami has been rising since the 1980's when research about the fifth basic taste began to increase. Much research is shared at the International Symposium on Umami, a gathering of people from around the world who study the four basic tastes. They have confirmed that umami is on its own and does not enhance other basic tastes. To determine if umami was its own taste, researchers had to prove that umami was not produced by any combination of other basic tastes, is independent of other basic tastes, has its own specific receptor for its taste and lastly, is found universally in many foods. All of these were found to be true.
